Kort beskrivning
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 9 - 12; Ryggkotor: 44 - 49. Diagnosis: large species (Ref. 34006, 78218). Tooth patches broad; obliquely angled pectoral fins positioned low on body (Ref. 44050). 17-49 (Ref. 34006) or 44-45 (Ref. 44050) vertebrae. 9-12 anal-fin rays; 19 caudal-fin rays (ii-7-8-ii); eye typically oval (along horizontal axis); caudal saddle and bar pattern poorly developed, even in juveniles; body with relatively small spots and flecks; pectoral and pelvic fin rays unpigmented (Ref. 44050). Broader mouth than M. microstoma, and fewer gill rakers and more vertebrae than either M. microstoma and M. tanganyikaensis; small dark marks rather uniformly distributed over the entire body and caudal fin, with no distinct dark or pale bars or bands, as M. microstoma and M. tanganyikaensis (Ref. 34006).
Female reaches up to 42.0 SL; carnivorous, feeding on fishes, crabs, and other aquatic creatures (Ref. 44050).
